A paroled drug dealer, wanted for the execution-style murder of an undercover Maryland state trooper during a drug sting last month in Washington, D.C., was nabbed in Brooklyn yesterday.

Kofi Orleans-Lindsay, 23, faces an extradition hearing in Brooklyn federal court on Friday, when prosecutors will seek to return him to the District of Columbia to stand trial on first-degree murder charges.

Maryland State Trooper 1st Class Edward Toatley, 37, a 16-year veteran, was shot in the head and killed during an undercover drug buy Oct. 30 in northeast Washington. Toatley – a highly decorated trooper with a reputation for infiltrating drug gangs – had arranged a meeting with Orleans-Lindsay in a gas station to buy drugs.

Orleans-Lindsay pulled up in a silver Mercedes-Benz, got out, and climbed into the undercover cop’s car – a Toyota SUV equipped with audio and video cameras, law enforcement officials said. The dealer took $3,500 for the drugs, and got out of the car, police said.

About three minutes later, the surveillance equipment picked up Toatley saying, “Here he comes.” Moments later, Toatley is heard asking, “Is everything all right?” followed by a gunshot and the sound of the veteran cop “gasping for breath,” court papers show.

Orleans-Lindsay fled on foot and disappeared into the night, police said. Toatley, who was president of the Coalition of Black Maryland State Troopers, died hours later in a hospital, with his wife, Inez, and three children at his side.

A task force of FBI agents, New York City and Washington cops, Maryland troopers, and U.S. marshals tracked the dealer to a Queens motel, where he was hiding out. They arrested him around 1 a.m. yesterday as he drove alone on Atlantic Avenue in Brooklyn.

Orleans-Lindsay has been arrested five times since 1994, police in Washington said, on charges including drug dealing, car theft and burglary.

He was enrolled in a probation pilot program, under which drug-addicted ex-convicts were required to show up for twice-weekly drug tests. His first violation of the program was supposed to spark a reprimand, according to The Washington Post.

His fifth violation was supposed to trigger his arrest. After 72 violations, the report said, a probation officer apparently submitted a request for an arrest warrant, which was approved Oct. 31 – the day after Toatley was murdered.
